I believe the correct answer from the choices listed above is option A. A reaction that has reached equilibrium would mean that the reaction rates of the forward and reverse reactions are equal. Hope this answers the question. Have a nice day.

The correct option is A.

A chemical reaction is said to have reached an equilibrium stage if the rate of reaction of the forward reaction is equal to the rate of reaction of the reverse reaction. Two way arrows are usually used to depict equilibrium reactions. These arrows indicate that the chemical reaction can move both ways. At the equilibrium point the concentrations of both the reactants and the products are equal.

This is a mixture that has the same composition throughout.
FinnZ [79.3K]

Answer: Homogeneous mixture

Explanation:

Homogeneous mixtures are those mixtures in which the dispersed phase is uniformly distributed throughout the dispersion medium. The dispersed phase has uniform composition throughout the dispersion medium and thus there is no physical boundary between the dispersed phase and the dispersion medium. Example: salt in water

Heterogeneous mixtures are those mixtures in which the dispersed phase is not uniformly distributed throughout the dispersion medium. The dispersed phase does not has uniform composition throughout the dispersion medium and thus there is a distinct physical boundary between the dispersed phase and the dispersion medium. Example: Sand in water

Which of the following happens when a reaction reaches dynamic equilibrium in a closed system?
laiz [17]

Answer: B

Explanation:

At equilibrium, the rate of the forward reaction is equal to the rate of the reverse reaction, and thus the concentrations of the reactants and products must be constant.

An atom in an excited state contains more of what type of energy than the same atom in the ground state? An atom in an excited s
kupik [55]

Answer: An atom in an excited state contains more of kinetic energy than the same atom in the ground state.

Explanation:

Kinetic energy is the energy acquired by an object due to its motion. And, thermal energy is the internal energy of an object arisen because of the kinetic energy present within the molecules of the object.

Potential energy is the energy acquired by an object due to its position.

The total energy present at the center of mass of an object is known as mass-energy.

So, when an atom gets excited then it means it is gaining kinetic energy due to which it moves from its initial position after getting excited.

Thus, we can conclude that an atom in an excited state contains more of kinetic energy than the same atom in the ground state.
